Game-Changer for Shedding and Dry Scalp

The Genesis Serum Fortifiant Hair Serum has really helped reduce my hair shedding. It’s lightweight, absorbs easily, and doesn’t weigh my hair down or make it look oily like so many other products do. I’ve also noticed my dry scalp hasn’t flaked as much since using it. My hair feels healthier and fuller without any residue.

My Favorite Hair Oil for Smooth and Shiny Hair

[This review was collected as part of a promotion.] I have been using the Kerastase Elixir Ultime oil and it has honestly made such a difference in how my hair looks and feels. It gives my hair a smooth and glossy finish without leaving it greasy or heavy. I use one or two pumps on my mid lengths and ends, and it instantly softens everything and makes it look more put together.

Less shedding

[This review was collected as part of a promotion.] I have been using this serum for about a month now. I do really like the results. When I brush my hair there is less shedding seen. It’s started working about the second week of use. I don’t use the recommended 4 pippets simply because I want to be economical. I already bought a second one to continue its use after this first bottle is finished. I do have some itchiness happening but not too bad. I have used an oil to reduce that. I think it’s worth it.

What a Difference One Bottle Can Make!

I was hesitant to spend so much on hair serum. The smell was mild and it felt good on my scalp when my stylist recommended and applied due to my thinning, probably perimenopause-hair. It didn't make my hair look or feel greasy and my scalp felt better, even though I thought my scalp was normal before. I have always had fine hair, but I began to have thinning hair as well. Before I finished the bottle, I noticed increase density and hair growth. I tried to go cheaper and purchased another brand and was deeply disappointed. My initial results began to disappear. I immediately purchased again and will forever be a loyal Genesis Serum Fortifiant Hair Serum customer. Try a bottle, you won't be sorry!

Hair loss = gone

[This review was collected as part of a promotion.] Nothing like it I’ve ever tried. I always have suffered from almost extreme hair loss not from anything just in general I noticed my hair shedding a crazy amount within the last 2 months. I tired this serum and have used for 4 weeks 3 days on 1-2 days off and have notice a huge difference. I only lost 7 strands of hair on my last comb though compared to what it used to be 100’s literally uncountable

Miracle in a bottle

I had my doubts about this product, but decided to give it a try. After a few days, I noticed I was having a lot less free fall of hair. I use one squirt a day on different parts of my scalp. It does not leave your hair oily or sticky. If you are loosening too much hair, give this a try!

I also love pairing it with the 8H Magic Night Serum for the perfect hair routine. It’s a total game changer!

Way too strong of perfume

I really wanted to love this but unfortunately didn't use it long enough. The thin formula does soak in right away and its a faily big bottle for the price. The scent was way too strong for me. It smells good, clean fresh citrus almost but just way too strong! By the end of the day I had a headache from smelling it all day. Why are we still putting perfume fragrances in cosmetic products? This is supposed to be helping my scalp? I ended up returning.
